Installer.OnCommitting Method

This method is called before the Commit methods of the installers in this instance's InstallerCollection run.

Raising an event invokes the event handler through a delegate. For more information, see [<topic://cpconProvidingEventFunctionality>].

The OnCommitting method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

When overriding OnCommitting in a derived class, be sure to call the base class's OnCommitting method so that registered delegates receive the event.

The following example demonstrates the OnCommitting method of the Installer class. The OnCommitting method is overridden in the derived class. Space is provided for the user to add the steps to be performed before committing and after committing.

// Override the 'OnCommitting' method. 
protected override void OnCommitting(IDictionary savedState)
{
   base.OnCommitting(savedState);
   // Add steps to be done before committing an application.
   Console.WriteLine("The OnCommitting method of MyInstaller called");
}
